Ok, it appears in the folder, but not when I go to the level select. Also, I used Kitchen, not Bedroom.
Now, I made a map named TEST in the slopes, and that saved, I can choose it when I select a level. But since then I couldn't.
And when I go into the kitchen, open the editor and choose load map, all the levels are there including TEST, but not the one I'm working on.
Also, no, I don't know how.
